I don't understand why it's so trendy right now to design mecha that walk on itty-bitty tiptoe spikes. Don't get me wrong, your machine here is very cool and badass looking... but it would be constantly stabbing holes into the ground. Those spike tips would probably break off (or at least bend) real soon. Glad you at least put those pads/shields on them.
Also, I love how the front looks like a big helicopter.
Badass, looks awesome. And I gotta say, the legs kinda looks like the Spiderbot off from Supreme Commander 1 on the PC or the Xbox 360 (either 1, there the same). But yea, great work, keep up thee paste.
